Definitions

  • the invention relates to a brake caliper for a vehicle brake, in particular for a disc brake of a commercial vehicle, the brake caliper comprising a brake pad having a friction lining and a brake pad carrier configured to carry the friction lining proximate to a brake disc of the vehicle brake, wherein the friction lining has a contact surface facing away from the brake pad carrier which is configured to bear against the brake disc of the vehicle brake during braking, wherein the brake pad carrier has a carrier plane facing towards the friction lining and a rear plane opposite to the carrier plane, and a wear indication device having a fixation means and a signal wire comprising a looped portion, wherein the fixation means has a front part engaging the carrier plane, a back part engaging the rear plane and a bridge connecting the front part and the back part, wherein the looped portion of the signal wire is at least partly arranged externally on the front part of the wear indication device and projects therefrom towards the contact surface.
  • Brake calipers of the aforementioned type are generally known in the art and typically employed in trucks or buses.
  • the friction lining of such a brake caliper is configured to bear against a brake disc during braking, which in turn causes the friction lining to wear over time.
  • the wear indication device As the wear, i.e. consumption, of the friction lining caused by the rotation of the brake disc during the brake progresses, at some point a distal portion of the wear indication device will commence to be worn off, i.e. consumed, as well. Due to that, the distal portion of the wear indication device facing towards the friction lining and/or the brake disc is formed by a material that does not damage the brake disc but withstands high temperatures that occur during braking.
  • a signal wire is typically integrated in the distal portion of the wear indication device that is subject to wear. Once the wire is being ruptured by the rotation of the brake disc during braking, a voltage change is registered as a function of the rupture, indicating that the wear limit is reached. Only a residual amount of friction lining remains such that the vehicle can safely be taken to a maintenance station for brake pad replacement.
  • US 3675197 shows a wear indication device of the aforementioned type that allows an appropriate wear indication and mounting of the wear indication device to the brake pad carrier.
  • Said wear indication device comprises a fixation means for fixating the signal wire.
  • the fixation of the signal wire to the clip or brake pad basically relies on friction between the signal cable and the clip. Due to the friction-based fixation, it has been found that under certain conditions, the signal wire, in particular the looped portion of the signal wire, may loosen from the fixation means. When this occurs, the signal wire may rupture prematurely, i.e. earlier than intended, by the rotation of the brake disk during braking. In such case, a false or inaccurate indication is generated even before the actual wear limit is reached. This is highly unwanted. Furthermore, it has been observed that with known fixation means, signal wires have been erroneously assembled, for example too tight or too loose. When this happens, the overall accuracy of the wear limit indication is reduced.
  • a hook is proposed, wherein said hook is attached to the back part of the fixation means and wherein said hook is configured for engaging with said looped portion.
  • the invention advantageously recognized that by providing a hook attached to the back part of the fixation means the signal wire can be conveniently and securely mounted while the looped portion is properly tightened. In this way, the position of the looped portion and the signal wire as such is exactly determined and the looped portion is reliably kept in a defined position. Hence, the likelihood of false i.e. too early wear limit indications is reduced. Furthermore, the overall assembly process of the wear indication device is more repeatable and more mistake-proof.
  • the hook comprises a first portion extending from said back part, wherein said first portion is aligned substantially in parallel to said bridge.
  • the hook comprises a second portion extending form the first portion, wherein said second portion is aligned substantially in parallel to the back part and extends towards said bridge.
  • the fixation means comprises a cut-out located adjacent to said hook, in particular, wherein a geometry of said cut-out corresponds to a geometry of said hook.
  • said hook is formed integrally with said fixation means.
  • hook and fixation means are preferably manufactured as one-piece and in particular from the same material. In this way, the number of parts and the manufacturing complexity is reduced.
  • said looped portion comprises a loop protective sleeve arranged at said looped portion, wherein said loop protective sleeve is configured for protecting the signal wire at a portion at which the signal wire contacts said hook.
  • said signal wire comprises a main protective sleeve, wherein said main protective sleeve is configured to abut or to be pressed against said hook to secure the position of the looped portion and wherein said main protective sleeve overlaps with said loop protective sleeve.
  • the fixation means comprises a bar extending from the front part parallel to the carrier plane and wherein the bar is configured to engage the signal wire proximate to the carrier plane.
  • the signal wire is repeatable secured at a position where it is proximate to the carrier plane and the contact surface such that the signal wire will face towards and come into contact with the brake disc, where it will be ruptured when the predefined wear limit is reached.
  • the bar extends at a distance and parallel to the carrier plane.
  • the bar is preferably straight, but may also be partially or completely curved.
  • the brake pad carrier has a recess, in particular a through-hole, wherein said recess extends from the carrier plane to the rear plane, and wherein the signal wire is led there through.
  • a secure and reliable guidance of the signal wire through the brake pad carrier is achieved.
  • the looped portion of the signal wire is at least partially looped around the bar, extends through the recess and is looped around the hook. In this way, the signal wire is safely and repeatable secured to the fixation means.
  • the fixation means has a recess configured to guide the signal wire, wherein the recess at least partially overlaps the recess of the brake pad carrier, and a back end portion of the signal wire is led through both recesses.
  • the signal wire and, in particular, its back end can be guided from the rear plane to a connector which can be used to connect wear indication device to a control unit of a vehicle.
  • the fixation means has a positioning means configured to engage a circumferential surface of the through-hole, thereby arranging the fixation means at a predefined position with respect to the through hole.
  • the fixation means is secured parallel to the carrier plane by the positioning means and additionally orthogonal to the carrier plane by the clamping force acting on the carrier plane and the rear plane, respectively.
  • Such a positioning means securely arranges the fixation means with respect to the through-hole and at the same time provides a repeatable positioning of the signal wire which ensures a safe detection of the wear limit.
  • the bridge is configured to rest against an upper surface of the brake pad carrier.
  • the fixation means can be coupled to the brake pad carrier by pushing the fixation means from the upper surface of the brake pad carrier along the carrier plane and rear plane into its final position.
  • the final position of the fixation means with respect to the carrier plane is advantageously secured by the bridge which rests against an upper surface of the brake pad carrier.
  • the invention also relates to a wear indication device for a brake caliper, in particular a brake caliper according to any of the preceding embodiments, wherein the brake caliper comprises a brake pad, the brake pad having a friction lining and a brake pad carrier configured to carry the friction lining approximate to a brake disc of the vehicle brake, and wherein the friction lining has a contact surface facing away from the brake pad carrier which is configured to bear against the brake disc of the vehicle brake during braking, and a wear indication device having a fixation means and a signal wire comprising a looped portion, wherein the fixation means has a front part engaging the carrier plane, a back part engaging the rear plane, and a bridge connecting the front part and the back part, wherein the looped portion of the signal wire is at least partially arranged externally of the front part of the wear indication device and projects therefrom towards a contact surface.
